Scrambler
Yes, that worked. The actual flashing happened after a first reboot, where a menu appeared, and I pressed ENTER on the relevant item (“Start Flashing…” or something, I can’t remember what it said exactly). I assume it was the same for you.
Still, while I can successfully boot into a live USB Linux (e.g., Fedora), after completing the installation, as I get past the bootloader, the screen goes black. I suppose this happens when switching to modesetting. Booting Fedora in “rescue mode” works.
Other people don’t seem to have this issue, so I suspect it must be some issue between the graphics driver and my screen setup (I am connecting a DELL U3425WE through Thunderbolt 4).
